Txheej txheem cej luam
Kev tsim thiab kev ua haujlwm ntawm SIMATIC PS307 ib-theem load fais fab mov (lub kaw lus thiab thauj khoom tam sim no) nrog kev hloov pauv tsis siv neeg ntawm cov khoom siv hluav taws xob yog qhov kev pom zoo rau SIMATIC S7-300 PLC. Cov khoom siv rau CPU tau tsim sai sai los ntawm txoj kev sib txuas uas tau muab nrog lub kaw lus thiab thauj khoom tam sim no. Nws kuj tseem tuaj yeem muab 24 V muab rau lwm yam S7-300 system Cheebtsam, input / output circuits ntawm input / output modules thiab, yog tias tsim nyog, cov sensors thiab actuators. Cov ntawv pov thawj zoo xws li UL thiab GL pab kom siv tau thoob ntiaj teb (tsis siv rau kev siv sab nraum zoov).
Tsim
Lub kaw lus thiab cov khoom siv thauj khoom tam sim no raug ntsia ncaj qha mus rau S7-300 DIN rail thiab tuaj yeem txuas ncaj qha mus rau sab laug ntawm CPU (tsis muaj kev tshem tawm yuav tsum tau ua)
Diagnostics LED rau qhov taw qhia "Cov zis hluav taws xob 24 V DC OK"
ON / OFF keyboards (kev ua haujlwm / stand-by) rau kev sib pauv ntawm cov modules
Strain-relief sib dhos rau input voltage txuas cable
Muaj nuj nqi
Kev sib txuas rau tag nrho 1-theem 50/60 Hz tes hauj lwm (120 / 230 V AC) los ntawm kev hloov pauv tsis siv neeg (PS307) lossis phau ntawv hloov pauv (PS307, sab nraum zoov)
Short-term fais fab tuag backup
Cov zis hluav taws xob 24 V DC, stabilized, luv Circuit Court-pov thawj, qhib Circuit Court-pov thawj
Parallel kev sib txuas ntawm ob lub zog siv rau kev txhim kho kev ua tau zoo
